Viagra vs Cialis vs Levitra - Which is best?

Sildenafil was a drug being investigated by Pfizer for treating blood pressure. It flunked the stringent FDA criteria to make the grade, but as the story goes, the men participating in the study began snickering about all the erections they were having. And the rest, as they say, is history.

What is Erectile Dysfunction (ED)?

Erectile dysfunction (ED)—formally called impotence—is a failure to have or maintain an erection, which is sexually crippling. Along with premature and other ejaculatory abnormalities, it is one of the categories of sexual dysfunction in men.

The penis normally has a mechanism by which engorgement with blood expands the flaccid, erectile tissues such that penetration in intercourse is possible. Erectile dysfunction—or, ED—affects up to 40% of men over 40 and 70% over 70.

What’s going on? Is it a mutation? A new type of zombie apocalypse?

Why is ED getting to be so common?

We were never meant to last as long as we do. As our technology evolved faster than our physical bodies, advances that resulted in increased life expectancy brought with them age-related diseases never seen when we were all expected to be dead before age 40. Heart disease is new for us. Cataracts, Type II diabetes, atherosclerosis, prostate enlargement and cancer, and even menopause—all new. This baggage also includes erectile dysfunction, since age is a prominent risk factor.

Everyone began throwing their hats in the ED ring

When Pfizer made billions from their Viagra and with reports of 80% or greater rates of successful penetration, it wasn’t long before other ED drugs hit the market to cash in on this lucrative niche, filling the vacuum created and maintained by the sometimes perceived embarrassment and humiliation of ED.

Enter vardenafil (Levitra) and tadalafil (Cialis), which soon joined the ranks of options, fine-tuning the properties and earning patents—and patients—in their own right. After adequate assessment for causes of ED—circulatory, low testosterone, anatomical, psychological—if all that was needed were something to open the erectile tissues to increased blood flow, relief from this sexual dysfunction was just a prescription away...or not… but buying Viagra without a prescription is not such a good idea. Read why in the article OTC Viagra-A Bad Idea.

Which to choose? Viagra? Cialis? Others?

Once Viagra proved its mettle, the race was on to compete. Not only content to just offer another Viagra knock-off, drug companies searched for properties they could tweak to give their own contenders a competitive edge. This is the arena where the pros and cons of the different drugs could guide one’s choice:

Chemical structure. Viagra and Levitra both have a similar chemical structure. Cialis is a different chemical structure altogether. Mainly of academic interest. They all work the same, inhibiting the enzymes that degrade nitric oxide, the chemical needed to open blood vessels for increased circulation.

The timing of taking it

Viagra requires an empty stomach to be its most effective.

Levitra and Cialis do not.

Viagra, Levitra, and Cialis all create some loss of romantic spontaneity, since they should be taken before a planned intercourse.

Cialis, however, offers a daily scheduling option, making intercourse something that can just happen, anytime, anywhere (careful!). This benefit has been used to great advantage in its television advertising.

A newer FDA-approved drug, avanafil (Stendra), boasts a 15-minute onset of action, as opposed to about an hour for the others.

Side effects and contraindications

Because they all have a similar mechanism of action, they all have the same side effects and contraindications:

Headaches

Dyspepsia (stomach complaints)

Vasodilation and hypotension

Diarrhea

Runny nose

Nosebleed

Priapism (prolonged, painful erection)

Blue vision and other visual disturbances (primarily with Viagra)

Contraindicated with nitrates, certain antibiotics, and antifungals, in liver and kidney impairments, and in men not heart-healthy enough for sex.

Duration of action

Viagra and Levitra both last for about four hours. Cialis can last over a day.

While this may seem to tip the decision toward Cialis, one must keep in mind that if it lasts longer, one is stuck with it longer, which can be sobering when encountering some emergency requiring medications that might mix badly with it.

Which one is best?

There are multiple options for those who seek relief from ED. A Clinical Practice Guideline from the American College of Physicians (ACP) recommends that the choice be based upon on the patient's preferences, including cost, ease of use, desired duration of action, and adverse effects.3

Hormonal balance is very important; when the hormones are properly balanced, the body works as expected. But when they are out of balance, the body begins experiencing problems.

Your Options To Treat Erectile Dysfunction Extend Beyond Viagra
When sildenafil began marketing in 1998, the drug company Pfizer sold half a billion dollars’ worth of its brand name, Viagra, in its first quarter. It was luck when the drug failed its study as an antihypertensive, but its male participants began reporting all of the erections they were experiencing.
Now there was a drug which took the closeted “impotence” out into the open, made it a “dysfunction,” and offered a treatment for it. Because it did not cure erectile dysfunction (ED) and required continued use, for Pfizer it was the gift that kept on giving.
Today, there other colors the “little blue pill” has to compete with—orange: tadalafil (Cialis); and yellow: vardenafil (Levitra).
Choosing Levitra, Viagra, or Cialis
Cialis is dubbed “the weekend pill” because it can last up to 36 hours; the two that are the most alike, however, are Levitra and Viagra. ...

Failure or misuse of birth control is a primary cause of unplanned pregnancies. Being pregnant attracts different feelings, to some, it is a joy after much waiting. To others it is stressing since the last thing on your mind was to become pregnant. Whichever the case, it is crucial to learn when you can become pregnant to take advantage of the circumstance to attain a pregnancy if that’s your goal; or to avoid the situation if not ready to become pregnant. It is a misconception that a woman can’t become pregnant during her period after having sex. What is a period? For every woman of childbearing age, every month, the lining of the uterus becomes thicker in preparation for pregnancy after an egg is fertilized. If the egg is not fertilized, the lining is shed off as blood via the vagina. The process is known as period or menstruation. But what are chances of getting pregnant on your period?
